Han’s CNC’s main business is the research and … Continued
When designing high-level circuit boards, multi-layer circuit boards are usually used instead of single-layer and double-layer circuit boards. Why is this? Today, I brought you the reasons why multilayer boards are used for high-speed circuit boards! Let’s take a look! Multi-layer boards have many characteristics that single-layer boards and double-layer boards do not have. It … Continued
Circuit board design software generally includes two major modules: schematic design and PCB design. The current mainstream circuit board design software are PROTEL, ORCAD, VIEWLOGIC, POWERPCB, CADENCEPSD, MENTORGRAPHICES Expedition PCB, Zuken CADSTART, WINBOARD/WINDRAFT/IVEX-SPICE, PCB Studio, TANGO, PCBWIZARD (PCB production software package supporting LIVEWIRE) ), ultiBOARD7 (PCB production software package supporting multiSIM2001) and so on. PROTEL … Continued
Why is PCB green? Why are most PCBs green? This is the most basic question. In fact, the circuit board itself is brown, and the green we see is the solder mask. The solder mask is not necessarily green, but green is the most common. As for why the green solder mask should be used, … Continued
FPC board refers to single, double and multi-layer flexible copper foil substrates with polyimide (PI) or polyester (PET) as the base material, including adhesive and non-adhesive flexible copper foil substrates. The purpose of FPC board testing is to establish a general rule for the appearance and quality of FPC boards. The basis for judging the … Continued
Flexible board FPC used to be called chaotically. It was first called soft board, and later it was also called flexible board, flexible printed circuit board and so on. Rigid-flex printed board refers to a printed board that contains one or more rigid areas and one or more flexible areas, which are composed of rigid … Continued
HDI is the abbreviation of High Density Interconnect. It is a (technology) for the production of printed boards. It is currently widely used in mobile phones, digital (camcorder) cameras, MP3, MP4, etc., and is generally manufactured by build-up. The more the number of layers, the higher the technical grade of the panel. Ordinary HDI boards … Continued
The advantages of infrared thermal imaging camera for temperature measurement. In the recent,outbreak of the Covid-19, fever usually appears as the first symptom after infection. Temperature measurement become the main method for suspected cases. Especially in crowded places such as hospitals, subway stations, and railway stations. At present, the most common temperature measurement tools on … Continued
Hard Board meets extreme difficulty from the very begaining Epidemic but later resumed fast because of 5G. Huawei is on the top one class in developing 5G technology. The 5G communication business opportunity extends to notebooks. Not only are major mobile phone chip manufacturers entering the layout, but also brand manufacturers have announced or launched … Continued
Rigid Board fabrication(PCB,FPC,METAL CORE Circuit etc) will generate many pollutant, so how to process the wastewater is a big challenge. PCB wastewater is divided into cleaning wastewater, ink wastewater, complex wastewater, concentrated acid waste liquid, concentrated alkali waste liquid and so on. Wastewater has many types of pollutants and complex components. The rational treatment of … Continued
The Critical Role of Solder Mask Selection in soft and hard boards Soft and hard boards are separated whether they can be bent. The solder mask (SM), often referred to as the “green layer,” is an indispensable protective coating applied to printed circuit boards (PCBs). Its primary function is to insulate copper traces, prevent solder … Continued
